N300 Wifi Extender - Keeps disconnecting.

So I plugged my ethernet cord into my extender. I start playing a video game and I suddenly disconnect. I got back on and was able to start a new game. Whenever I'm playing anything after about 20 minutes, it disconnects me. The extender still provides wirelessly, but the ethernet stops working. I turned off the power saving mode and I have upgraded its software always. It still just logs me out. Is there anything I can do to prevent this?
